The branch of medicine that is focused on the treatment, diagnosis, and study of disorders of the lower leg, ankle and foot is referred to as podiatry. Because people often spend a great deal of their time on their feet, many problems in this area can occur. A person seeks help from the field of podiatry when they need treatment for heel spurs, bunions, arch problems, deformities, ingrown toenails, corns, foot and ankle problems, infections, and problems with the foot that are related to diabetes and additional diseases.

To treat problems of the foot, ankle or lower leg, a podiatrist may prescribe physical therapy, drugs, perform surgery, or set fractures. Individuals may also be recommended to wear corrective shoe inserts, custom-made shoes, plaster casts and strappings in order to correct deformities.

When trying to gather information on a patient problem, a scanner or force plate may be used in order to design orthotics. During this procedure, patients are told to walk across a plate that is connected to a computer; the computer then takes a scan of the foot and indicates weight distribution and pressure points. The computer readouts will give the podiatrist information to help them determine the correct treatment plans.

Diagnosis is also provided through laboratory tests and x-rays. Through the foot, the first signs of serious problems such as heart disease, diabetes and arthritis can show up. For example, individuals that have diabetes may frequently have problems such as infections and foot ulcers because they experience poor circulation in the foot area. A podiatrist can then have consultations with patients when symptoms arise. Referrals will then be made to specialists that handle the greater health problems.

Some podiatrists have their own independent, private practices or clinics where they have a small staff and administrative personnel. Many podiatrists work within group practices. They usually spend time performing surgery in ambulatory surgical centers or hospitals, or visit patients in nursing homes. Podiatrists typically spend between 30 to 60 hours of week working. Some podiatrists specialize in public health, orthopedics, surgery, or primary care. Other fields include specialties in geriatrics, dermatology, pediatrics, diabetic foot care and sports medicine.

Some podiatrist specialists complete extra training in the area of foot and ankle reconstruction that results from the effects of physical trauma or diabetes. There are also surgeons that perform surgery of a cosmetic nature to correct bunions and hammertoes.

Diabetes affects millions of people every year. Blood vessels located all over the body are damaged due to diabetes—even the blood vessels of the feet. Neuropathy, or nerve damage, can result from slower blood flow in the legs and feet. In diabetic patients, neuropathy is very important to monitor, as diabetics are at risk for developing ulcers.

Always washing and thoroughly drying the feet are pertinent parts of diabetic foot care. There should be a focus on cleaning between the toes. Even if no pain is felt, the entire foot should be examined for redness and sores. Neuropathy can often mask the pain of sores and ulcers and can cause these conditions to be overlooked. Use a mirror to examine the underside of your feet if needed. It is recommended that diabetics wear well-fitting socks.

Patients with diabetes should have their doctor monitor their blood levels because blood sugar levels play a huge role in diabetic care. Monitoring these levels on a regular basis is highly advised. It is very important to keep your blood sugar levels in the normal range, which can be determined by your physician. There are medications that may be prescribed to help with any neuropathy experienced by the diabetic patient. It is also advisable to visit a podiatrist if one is experiencing any conditions involving the feet, such as ingrown toenails, which in more severe cases can cause infection.

Diabetic feet must be inspected daily. Diabetic foot care at home is possible if a patient is provided with instructions from their podiatrist. Patients can relieve dry heels with creams or ointments. Suspected wounds should warrant an immediate call to the podiatrist. Gangrene is a serious problem for diabetics and can lead to sepsis and amputation in its worst cases. Early treatment and daily inspection of diabetic feet are keys to staying healthy.

Flatfoot is a condition that occurs when the arches on the foot are flattened, which allows the soles of the feet to touch the floor. Flatfoot is a common condition and it is usually painless.

Throughout childhood, most people begin to develop arches in their feet, however, some do not. Those who do not develop arches are left with flatfoot. The pain associated with flat feet is usually at its worse when engaging in activity. Another symptom that may occur with those who have this condition is swelling along the inside of the ankle.

It is also possible to have flexible flatfoot. Flexible flatfoot occurs when the arch is visible while sitting or standing on the tiptoes, but it disappears when standing. People who have flexible flatfoot are often children and most outgrow it without any problems.

There are some risk factors that may make you more likely to develop flatfoot. Those who have diabetes and rheumatoid arthritis have an increased risk of flatfoot development. Other factors include aging and obesity.

Diagnosis for flat feet is usually done by a series of tests by your podiatrist. Your podiatrist will typically try an x-ray, CT scan, ultrasound, or MRI on the feet. Treatment is usually not necessary for flat foot unless it causes pain. However, therapy is often used for those who experience pain in their flat feet. Some other suggested treatment options are arch supports, stretching exercises, and supportive shoes. 

An ingrown toenail is a nail that has curved downward and grows into the skin.  This typically occurs at the nail borders, or the sides of the nail.  As a result, pain, redness, swelling, and warmth may occur in the toe.  If a break in the skin forms due to the ingrown nail, bacteria may enter and cause an infection in the area; this is typically characterized by a foul odor and drainage.

Ingrown toenails have multiple reasons for developing.  In many instances, the condition is a result of genetics and is inherited.  The most common cause, however, is improper trimming; cutting the toenails too short forces the skin beside the nail to fold over.  An ingrown toenail can also develop due to trauma, such as stubbing the toe, having an object fall on the toe, or participating in activities that involve repeated kicking or running.  Wearing shoes that are too tight or too short can also cause ingrown toenails.

Treatment for an ingrown toenail varies between patients and the severity of the condition.  Milder cases that don’t involve infection or other medical conditions can benefit from soaking the feet in room-temperature water and gently massaging the side of the nail.  In most cases, however, it is best to see your podiatrist for thorough and proper treatment.  After examining your toe, your podiatrist may prescribe oral antibiotics to clear the infection if one is present.  Surgical removal of either a portion of the nail or the entire nail may also be considered.  In some cases, complete removal or destruction of the nail root may be required.  Most patients who undergo nail surgery experience minimal pain afterward and can return to normal activity the following day.

Ingrown toenails can be prevented with proper nail trimming and by avoiding improper-fitting shoes.  When cutting the toenails, be sure that you are cutting in a straight line and avoid cutting them too short.  Shoes should not be too short or tight in the toe box.

Tarsal tunnel syndrome is a condition in which the tibial nerve, located in the tarsal tunnel in the foot, is compressed. The tibial nerve can become compressed from injury, such as an ankle sprain, flat feet, and lesions. Arthritis, diabetes, and varicose veins can also cause swelling and thus result in nerve compression.

Symptoms of tarsal tunnel syndrome include several different sensations in the sole of the foot, inside the ankle, and around the tibial nerve. These sensations include shooting pains, numbness or reduced sensation, pins and needles, burning, and tingling. Symptoms tend to worsen with greater activity to the area. In rare and severe occasions, this can change the muscles in the foot.

If you suspect you have tarsal tunnel syndrome, you should consult with your podiatrist. He or she will examine your medical history to see if you have a history of diabetes, arthritis, or flat feet. They will also check to see if you have suffered an injury to the area recently. An electrical test will be conducted to check if the nerve has been damaged. A simpler Tinel’s Test might also be used. This includes simply tapping the nerve to create a sensation. An MRI scan of the area may also be used.

Treatments vary greatly for tarsal tunnel syndrome. Treatments include both nonsurgical and surgical options depending upon the severity of the condition. Nonsurgical options include anti-inflammatory medication and steroid injections to the area. Orthotics, such as a splint or brace that immobilizes the foot, is another noninvasive option. For those with flat feet, custom shoes can be made to offer better foot support. Surgical options include a tunnel tarsal release, in which an incision is made behind the ankle down to the arch of the foot. This releases the ligament and relieves pressure off the nerve. Some doctors use a more minimally invasive surgery, where smaller incisions are made in the ankle and the ligament is stretched out.

If you are suffering from painful sensations in your foot, see a podiatrist who can determine if you are experiencing tarsal tunnel syndrome. Tarsal tunnel syndrome that is left unchecked can cause permanent nerve damage to the foot.
